I have my solar array wired and operating. The readout on my CC says 14.7 volts going to the batteries. Now when I turn on the inverter i only get 108 volts from the 110 socket. Have i made a mistake along the line from the panels to the inverter? After spending all this money i don't have a voltage that will run my Dremel. What next? need all the help i can get at this point.
